CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. application Ser. No. 12/762,539, filed on Apr. 19, 2010 (abandoned), which, in turn, is a continuation of U.S. application Ser. No. 12/168,400, filed on Jul. 7, 2008 (pending), both of which are hereby incorporated by reference herein in their entirety.

FIELD

The present invention relates generally to compositions comprising a probiotic component as a pet food supplement, methods of making the same, and packaging. More particularly, the present invention relates to a pet food composition as a supplement that comprises a probiotic component, a sweetener component, and a fat component, methods of making the supplement, and packaging of the supplement.

BACKGROUND

Compositions containing probiotic microorganisms are desirable, especially in the pet food art. While various commercial attempts have been made to achieve such compositions, many of these do not provide sufficient efficacious levels of probiotic microorganism whether in live or dormant state due to issues associated with susceptibility of the microorganism to standard commercial pet food manufacturing procedures. For example, with pet food compositions in particular, efforts of coating or filling standard pet food kibbles with probiotic microorganisms have been suggested but, in practice, often prove impractical. To avoid issues associated with standard commercial food manufacture, other manufacturers may provide jars or probiotic microorganism powder for sprinkling on standard foods. However, this method raises issues of convenience and compliance such that still further development in this area is necessary to achieve an efficacious composition and method of making the same that will be successful in the marketplace and gain widespread human use and use with pets. Furthermore, powder forms of probiotic microorganisms are not stable enough because as soon as powder forms are exposed to the ambient environment, moisture in the environment promotes premature activation of the probiotic microorganisms.

Thus, a probiotic in a very stable form is needed. Moreover, the stable form should be easily administrable such that the consumer is able to administer it to the pet and be sure that the pet is ingesting the probiotic. Furthermore, the probiotic microorganisms should be in a controllable amount such that the owner knows that the pet is receiving a specific dose of the probiotic. Upon ingesting, the probiotic form should be able to survive in the pet until it reaches and becomes live and active in the gastrointestinal tract.

Therefore, a stable, easily administrable, survivable, and controllable dosing probiotic composition and process for making the same are needed.

SUMMARY

A pet supplement is provided and comprises an amount of probiotic microorganisms coated with a first fat component having a first melting point and a source of a sweetener component comprising sugar and a second fat component having a second melting point. The second melting point is higher than the first melting point. Methods of making the pet supplement are also provided.

Definitions

As used herein, the term “pet” is defined by a domestic animal, including, but not limited to, domestic dogs, cats, horses, cows, ferrets, rabbits, pigs, and the like. Domestic dogs and cats are used in exemplary embodiments of the present invention.

As used herein, the term “viable probiotic microorganism” or the like is defined by a probiotic microorganism in its live state, which by definition herein includes, but is not limited to, those in the dormant state and spores.

As used herein, the term “supplement” is defined by a form of a pet food, such as a tablet, capsule, or the like, or other forms such as biscuits, chews, edible films or other treats, which are intended to be used not as entire pet meals but in addition to regularly consumed pet food meals.

The present invention relates to a pet food composition as a supplement that comprises a probiotic component, a sweetener component, and a fat component, methods of making the same, and packaging for the supplement.

Compositions of the Present Invention

The present invention relates to compositions that may be sufficiently stable such that probiotic microorganisms are still live or dormant in the compositions at the time of ingestion by a mammal, thereby maintaining activity of the microorganism. The compositions can comprise: (a) a probiotic component; (b) a sweetener component; and (c) optionally a cocoa butter component.

As discovered herein, it is found that the sweetener component can be useful as a flowing agent to promote processing of the composition. Without the use of the sweetener component, certain problems can arise, including bubbling and unsmooth flowing.

The composition may be of any form that is orally administrable. For example, the composition may be in the form of tablets, capsules, supplements, or the like. Other forms may include powders comprising the probiotic and sweetener components, for use in combining with foods ordinarily consumed by a mammal.

In one embodiment, the composition is a pet food composition. As used herein, the term “pet food composition,” means a composition that is intended for ingestion by the pet. Pet food compositions may include, without limitation, nutritionally balanced compositions suitable for daily feed, as well as supplements (e.g., treats, edible films), which may or may not be nutritionally balanced. As such pet food compositions, or components thereof, may or may not be nutritionally balanced. As used herein, the term “nutritionally balanced,” with reference to the pet food composition or a component thereof, means that the composition or component has known required nutrients to sustain life in proper amounts and proportion based on recommendations of recognized authorities in the field of pet nutrition, except for the additional need for water.

Pet food compositions are readily understood in the art to be, for example, dry foods (e.g., at least partially extruded kibbles) and less brittle foods (e.g., semi-moist foods), or mixtures thereof. Pet food compositions may also be supplements, for example, tablets, capsules, or the like, or other forms such as biscuits, chews, edible films or other treats.

The probiotic component and the sweetener component can be described as follows:

The Probiotic Component

The probiotic component may comprise one or more yeast or bacterial probiotic microorganisms suitable for pet consumption and effective for improving the microbial balance in the pet gastrointestinal tract or for another benefit, such as disease or condition relief or prophylaxis, to the pet.

See, for example, WO 03/075676, to Societe Des Produits Nestle, published Sep. 18, 2003, and WO 07/126990A2, to Nestec, published Nov. 22, 2007.

The probiotic component can be any of a number of genera of bacteria. Non-limiting examples of the genera of bacteria include Bacillus, Bacteroides, Bifidobacterium, Enterococcus (e.g., Enterococcus faecium DSM 10663), Lactobacillus, and Leuconostoc, and combinations thereof. Those of the genera Bacillus may form spores. In one embodiment, the probiotic component does not form a spore. Non-limiting examples of lactic acid bacteria suitable for use herein include strains of Streptococcus lactis, Streptococcus cremoris, Streptococcus diacetylactis, Streptococcus thermophilus, Lactobacillus bulgaricus, Lactobacillus acidophilus (e.g., Lactobacillus acidophilus strain DSM 13241), Lactobacillus helveticus, Lactobacillus bifidus, Lactobacillus casei, Lactobacillus lactis, Lactobacillus plantarum, Lactobacillus rhamnosus, Lactobacillus delbruekii, Lactobacillus thermophilus, Lactobacillus fermentii, Lactobacillus salivarius, Lactobacillus reuteri, Bifidobacterium longum, Bifidobacterium infantis, Bifidobacterium bifidum, Bifidobacterium animalis, Bifidobacterium pseudolongum, and Pediococcus cerevisiae, or mixtures thereof, preferably Lactobacillus salivarius, Bifidobacterium infantis, or mixtures thereof.

As a non-limiting example, strains of Bifidobacteria isolated from resected and washed canine gastrointestinal tract as disclosed in U.S. Publication Nos. 2005/0152884; 2005/0158293; 2005/0158294; and 2005/0175598A1, along with WO05060707A2 can be used. Strains isolated from resected and washed feline gastrointestinal tract may be particularly useful. Non-limiting examples of feline strains that can be used are disclosed in U.S. Publication Nos. 2006/0269534 and 2006/0270020.

In one embodiment, the compositions of the present invention can have a viable probiotic microorganism count of at least about 10⁵ colony forming units (CFU) per gram of composition, or at least about 10⁶ CFU per gram of composition, or at least about 10⁸ CFU per gram of composition. For example, the composition may have a viable probiotic microorganism count of up to about 10¹⁴ CFU per gram of composition, up to about 10¹² CFU per gram of composition, or up to about 10¹⁰ CFU per gram of composition, or up to about 10⁹ CFU per gram of composition. CFU is determined using the method provided as part of the European Pharmacopoeial Methods, 2003, Section 2.6.12. Advantageously, the composition provided herein has a shelf life of at least about three months, alternatively at least about six months, alternatively from about three months to about twenty-four months, alternatively from about six months to about eighteen months. As used herein, the term “shelf life” refers to that property of the composition whereby about 1% or more, alternatively about 5% or more, alternatively about 10% or more, alternatively about 25% or more, alternatively about 50% or more, alternatively about 75% or more, of the probiotic microorganisms of the composition are live viable and active at the referenced time period after exposure to ambient environmental conditions.

As further examples, the compositions may comprise at least about 0.001%, alternatively at least about 0.01%, alternatively at least about 0.1%, alternatively at least about 0.5%, and alternatively at least about 1% of the probiotic component, by weight of the composition. As further examples, the compositions may comprise about 99% or less, alternatively about 75% or less, alternatively about 50% or less, alternatively about 25% or less, alternatively about 10% or less, and alternatively about 5% or less of the probiotic component, by weight of the composition.

The Sweetener Component

The compositions herein comprise a sweetener component, which can be found useful as a flowing agent of the composition during processing. Without the use of the sweetener component, certain problems can arise, including bubbling and unsmooth flowing. The sweetener component, as defined herein, can comprise a monosaccharide, disaccharide, or any mixture thereof.

In one embodiment, the compositions herein comprise a monosaccharide. The monosaccharide utilized herein is of the general formula C_(n)H_(2n)O_(n), wherein n is an integer equal to or greater than 3. Non-limiting examples of monosaccharides that may be used include sorbitol, mannitol, erythrose, threose, ribose, arabinose, xylose, ribulose, glucose, galactose, mannose, fructose, sorbose, and any mixture thereof. In one embodiment, the monosaccharide may include sorbitol, mannitol, glucose, mannose, fructose, or any mixture thereof. In another embodiment, the monosaccharide is sorbitol.

In one embodiment, the compositions herein comprise a disaccharide. The disaccharide utilized herein is of the general formula C_(n)H_(2n)-2O_(n-1), wherein the disaccharide has 2 monosaccharide units connected via a glycosidic bond. In such formula, n is an integer equal to or greater than 3. Non-limiting examples of disaccharides that may be utilized herein include sucrose, maltose, lactitol, maltitol, maltulose, lactose, and any mixture thereof. In another embodiment, the monosaccharide is sucrose.

In one embodiment, which may be particularly advantageous to stability of the probiotic component wherein a sweetener component is utilized, the sweetener component comprises a monosaccharide or disaccharide having a melting point of from about 80° C. to about 140° C., or from about 90° C. to about 120° C. Non-limiting examples include monosaccharides, such as sorbitol or xylitol.

As examples, the compositions herein may comprise at least about 0.001%, or at least about 0.1%, or at least about 1%, or at least about 5%, or at least about 10%, or at least about 20% of the sweetener component, all by weight of the composition. As further examples, the compositions herein may comprise about 99% or less, or about 95% or less, or about 90% or less, or about 75% or less, or about 50% or less of the sweetener component, all by weight of the composition.

Many sweetener components can be used. The sweetener components associated with embodiments of the present invention can also be considered as sources of sweeteners in that they comprise not only a sweetener component but also other components. An example of a sweetener component, or what can be considered a source of a sweetener component, in accordance with one embodiment of the present invention is commercially available from the Blommer Chocolate Company of Chicago, Ill., and is commercially known as Blommer white kreemy coating. The Blommer white kreemy coating comprises a confectioner's white coating made from a blend of sugar, vegetable oils, nonfat milk powder, lecithin, and artificial color and flavor. More specifically, the Blommer white kreemy coating comprises sugar, partially hydrogenated palm kernel oil, nonfat milk powder, soy lecithin added as an emulsifier, monoglycerides, artificial color in the form of titanium dioxide, and artificial flavor. The Blommer white kreemy coating is generally a complete crystalline solid at 5° C. and begins crystallizing at 18° C. It begins melting at 23° C. and is in complete liquid phase at 38° C. Other white kreemy coatings are available from other manufacturers other than Blommer and can be used as well.

The final pet food composition, which can be in the form of a supplement, can comprise between about 8% and about 10% protein, between about 25% and about 35% fat, between about 1% and 1.5% crude fiber, between about 1% and 3% moisture/water, between about 2% and 3% ash and about 5×10¹⁰ CFU probiotic component, all per supplement. The supplement can be of many different sizes and weights.

Optional Components

The present composition may optionally comprise one or more further components, for example an optional component as described herein.

In one embodiment, the compositions may comprise, on a dry matter basis, from about 0.1% to about 30% crude protein, or from about 1% to about 20% crude protein, by weight of the composition. The crude protein material may comprise any material having a protein content of at least about 15% by weight, non-limiting examples of which include vegetable proteins such as soybean, cottonseed, and peanut, animal proteins such as casein, albumin, chicken, beef, pork, lamb, turkey, poultry and meat tissue and bacterial ingredients such as Lactobacillus, Bifidobacterium, Streptococcus, Enterococcus and Bacillus. Non-limiting examples of meat tissue useful herein include fresh meat, and dried or rendered meals such as fish meal, poultry meal, meat meal, bone meal, and the like. Other types of suitable crude protein sources include wheat gluten or corn gluten, and proteins extracted from microbial sources such as yeast.

The compositions may comprise a source of fat. In one embodiment, the compositions may comprise, on a dry matter basis, from about 0.5% to about 10% fat, from about 2.0% to about 5.0% fat, by weight of the composition. Sources of fat are widely known, and as used herein are interpreted to include (as examples) wax, fat, fatty acid, and/or lipid.

Specific examples of wax, fat, fatty acid, or lipid may often be interchangeable in accordance with nomenclature common in the art; for example, a lipid may often also be characterized as a fat. The inventors herein do not intend to be limited by any particular designation of nomenclature, and classifications of a particular material as a wax, fat, fatty acid, lipid, or the like is made for purposes of convenience only.

For example, the fat may comprise a cocoa butter component. As defined herein the cocoa butter component comprises one or more of cocoa butter, a cocoa butter extender, a cocoa butter replacer, or a cocoa butter substitute. A given fat may be classified as one of a cocoa butter extender, cocoa butter replacer, or cocoa butter substitute, or sometimes may be classified as two or more of a cocoa butter extender, cocoa butter replacer, and cocoa butter substitute. Where used, each of the cocoa butter extender, cocoa butter replacer, and cocoa butter substitute may be one particular fat within the referenced class or any mixtures of such fats.

Cocoa butter is commonly known in the art and may generally refer to the fat from cocoa beans used to prepare chocolate. Cocoa beans are obtainable from the pods of cocoa trees (e.g., Theobroma cocoa). Cocoa butter is commercially available from the Blommer Chocolate Company of Chicago, Ill. An example of a cocoa butter available from Blommer comprises their standard cocoa butter. This cocoa butter can be a prime pressed cocoa butter that has been mechanically pressed from properly roasted, winnowed, and milled blended chocolate liquor. Subsequent to pressing, the cocoa butter can be centrifuged to remove any remaining solids. The cocoa butter flavor can then be free from any off odors or off notes. The melting point can be around 30 to 35° C. Furthermore, the water activity of the cocoa butter can be below the required water activity levels to support the growth of microorganisms.

The cocoa butter component may additionally or alternatively comprise a cocoa butter extender. These extenders are also commonly known in the art, and may generally refer to other fats having solid fat index (SFI) profiles which are similar to cocoa butter. Cocoa butter extenders may comprise fat containing C₁₆ or C₁₈ fatty acids, or combinations thereof. Palm oil, shea oil, illipe butter, mango butter, salt butter, cottonseed oil, and soybean oil, including fractionated and/or partially hydrogenated forms, are non-limiting examples of cocoa butter extenders.

The cocoa butter component may additionally or alternatively comprise a cocoa butter replacer. These replacers will also be commonly known in the art, and may generally refer to fats having melting or other properties, or structures, similar to those of cocoa butter, which are based on non-lauric fats (e.g., C₁₆ or C₁₈). These include vegetable oils such as palm oil, cottonseed oil, soybean oil, and rapeseed oil, including fractions and/or partially hydrogenated forms thereof. One example is ASTRAL® R (partially hydrogenated vegetable oil (soybean oil and cottonseed oil), commercially available from Humko Oil Products, Cordova, Tenn.).

The cocoa butter component may additionally or alternatively comprise a cocoa butter substitute. These substitutes will also be commonly known in the art, and may generally refer to hard fats having melting or other properties, or structures, similar to those of cocoa butter, but which are based on lauric fats (C₁₂). Such cocoa butter substitutes may tend to have melting points higher than that of cocoa butter, making these substitutes interesting for imparting heat resistance to compositions. These include vegetable oils such as palm kernel oil and coconut oil, including fractions and/or partially hydrogenated forms thereof.

In one embodiment, the cocoa butter component comprises at least one lipid selected from the group consisting of soybean oil, cottonseed oil, coconut oil, rapeseed oil, palm kernel oil, fractions of the foregoing, and partially hydrogenated forms of the foregoing.

Alternatively or additionally, the fat may comprise an animal-derived fat component. As will be commonly known in the art, the animal-derived fat component comprises a fat derived from an animal. Non-limiting examples include beef, poultry, pork, and lamb (e.g., lards and tallows). Dairy fats may also be examples, including milkfat, fractionated milkfat, and butterfat.

In one embodiment, the fat may comprise a combination of a cocoa butter component and an animal-derived fat component at a ratio of from about 5:95 to about 95:5, or from about 5:95 to about 25:75, or from about 5:95 to about 50:50, all by weight. In another embodiment herein, the fat comprises the cocoa butter component and the animal-derived fat component at a ratio of from about 20:80 to about 45:55, or from about 25:75 to about 40:60, all by weight.

Alternatively or additionally, the fat may comprise a fatty acid. Illustrative sources include omega-3 or omega-6 fatty acids.

Omega-3-fatty acids are preferably derived from marine (fish) sources, including menhaden (a herring-like fish) and, as such, may be derived from such sources. Non-limiting examples of omega-3-fatty acid sources include docosahexaenoic acid (“DHA”) or eicosapentaenoic acid (“EPA”), such as OMEGAPURE, commercially available from Omega Protein, Inc., Houston, Tex. All forms of the fatty acid are also contemplated herein. For example, DHA is often provided as a triglyceride. As such, wherein a specific fatty acid is mentioned (e.g., “DHA”), such fatty acid includes the free form of the fatty acid as well as other forms such as the naturally occurring triglyceride or other form. The terms, DHA, EPA, or other specific terms are utilized for convenience as will be commonly understood in the art to include all forms of such termed material.

Omega-6-fatty acids may be utilized herein. As is well-understood in the art, omega-6-fatty acids are those fatty acid materials having a double bond positioned between the sixth and seventh carbon atoms of the fatty acid chain, when counting from the omega (distal) carbon atom of the chain.

Other examples of suitable fatty acids may include oleic acid, stearic acid, palmitic acid, and lauric acids, including suitable salts thereof. Even further examples of suitable fatty acids include esters or other derivatives thereof, such as cetyl palmitate, acetic, lactic, or citric mono- and di-glyceride fatty acids, isopropyl palmitate, isopropylmyristate, and mono-, di-, and triglycerides (some of which may also be characterized as fats).

The compositions may comprise a mixture of omega-3-fatty acids and omega-6-fatty acids, often through utilization of various materials containing these components. Certain compositions for use herein may be enriched in one or more specific omega-3-fatty acids or omega-6-fatty acids.

Alternatively or additionally, the compositions may comprise wax. For example, illustrative waxes include paraffin wax, beeswax (e.g., white or yellow), carnuba wax, candellila wax, microcrystalline wax, rice bran wax, cetyl ester wax, and emulsifying wax.

Alternatively or additionally, the compositions may comprise a polysaccharide such as shellac, chitin, chitosan or alginate.

The compositions herein may optionally comprise a source of carbohydrate. Grains or cereals such as rice, corn, milo, sorghum, barley, alfalfa, wheat, and the like are illustrative sources of carbohydrate. These carbohydrate sources, and typical levels thereof, are widely known.

The compositions may comprise a component such as dried whey or other dairy by-products.

The compositions may comprise a fermentable fiber. Fermentable fibers are well-known in the art. The fermentable fiber may be any fiber source which intestinal bacteria present in the animal can ferment to produce short chain fatty acids or other metabolic components. Non-limiting examples of such fermentable fibers include beet pulp (from sugar beet), gum arabic, gum talha, psyllium, rice bran, carob bean gum, citrus pulp, pectin, fructooligosaccharide, mannanoligofructose, soy fiber, arabinogalactan, galactooligosaccharide, arabinoxylan, and mixtures thereof.

In general, fermentable fibers are not digested by mammals but may be metabolized by intestinal bacterial species, such as Bifidobacterium. However, not all intestinal bacteria can metabolize fermentable fiber. In particular, bacteria such as Salmonella, E. coli and Clostridia are unable to process such fiber to any meaningful degree. This preferential digestibility, which is applicable for fermentable fiber as a class, can be used to improve the overall bacterial flora in the small intestine of the companion animal. Because fermentable fibers will only feed “good” bacteria such as Lactobacillus and Bifidobacterium, the amounts of harmful bacteria such as Salmonella, E. coli and Clostridia may decrease due to a reduction in food resources. Therefore, by providing a preferred food source for beneficial bacterial species, a diet supplemented with fermentable fiber can increase “good” intestinal bacteria while reducing the amount of “bad” bacteria.

Beet pulp and fructooligosaccharide, particularly short chain oligofructose, are particularly preferred fermentable fibers for use herein. As an example, fructooliogosaccharides are naturally occurring compounds which can be found in a variety of fruits or vegetables including banana, barley, garlic, honey, onion, rye, brown sugar, tomato, asparagus, artichoke, wheat, yacon, or chicory. Fructooligosaccharide may for example be provided as chicory root, as a long chain oligofructose (e.g., inulin), or as short chain oligofructose. Particularly useful herein are fructooligosaccharide comprising at least one of 1-kestose (abbreviated as GF₂), nystose (GF₃), and 1F-beta-fructofuranosylnystose (GF₄). While fructooligosaccharides can be extracted from plants such as those mentioned herein, they can also be formed artificially by adding one, two, or three fructose units to a sucrose molecule by a B-(2-1)-glycosidic linkage of the fructose unit(s) to the fructose unit of sucrose. As an example, fructooligosaccharides are commercially available under the tradename NUTRAFLORA from Golden Technologies Company, Incorporated (which is a short chain oligofructose comprising 1-kestose, nystose, and 1F-beta-fructofuranosylnystose). As another example, a mixture of short chain fructooligosaccharide and inulin can be PREBIO1 or a mixture of commercially available RAFTILOSE and RAFTILINE.

The fructooligosaccharide may be a short chain oligofructose, which will be well-known to those of ordinary skill in the art. Particularly useful herein are short chain oligofructose comprising 1-kestose (abbreviated as GF₂), nystose (GF₃), and 1F-beta-fructofuranosylnystose (GF₄). In a preferred embodiment, the short chain oligofructose comprises from about 25% to about 45% 1-kestose, from about 25% to about 45% nystose, and from about 1% to about 20% 1F-beta-fructofuranosylnystose, by weight of the short chain oligofructose, alternatively from about 30% to about 40% 1-kestose, from about 50% to about 60% nystose, and from about 5% to about 15% 1F-beta-fructofuranosylnystose, by weight of the short chain oligofructose. As an example, short chain oligofructose is commercially available under the tradename NUTRAFLORA from Golden Technologies Company, Incorporated (which is a short chain oligofructose comprising about 35% 1-kestose, 55% nystose, and 10% 1F-beta-fructofuranosylnystose, all by weight of the short chain oligofructose).

In an embodiment herein, the fermentable fibers may display certain organic matter disappearance percentages. In this optional embodiment, the fermentable fibers may have an organic matter disappearance (OMD) of from about 15% to about 60% when fermented by fecal bacteria in vitro over a 24 hour period. That is, from about 15% to about 50% of the total organic matter originally present is fermented and converted by the fecal bacteria. The organic matter disappearance of the fibers is alternatively from about 20% to about 50%, alternatively from about 30% to about 40%.

Thus, in vitro OMD percentage may be calculated as follows: (1−((OM residue−OM blank)/original OM))×100, where OM residue is the organic matter recovered after 24 hours of fermentation, OM blank is the organic matter recovered in corresponding blank tubes (i.e., tubes containing medium and diluted feces, but no substrate), and original OM is that organic matter placed into the tube prior to fermentation. Additional details of the procedure are found in Sunvold et al., J. Anim. Sci., Vol. 73, pp. 1099-1109 (1995).

In one embodiment herein, the compositions may comprise at least about 0.25% total fermentable fiber, by weight of the composition. By “total fermentable fiber” it is meant that the referenced level is determined by adding the relative amounts of each fermentable fiber present in the composition. For example, wherein a composition comprises 1% fructooligosaccharide and 0.5% beet pulp, by weight of the composition, and no other fermentable fiber, the composition comprises 1.5% total fermentable fiber, by weight of the composition. Alternatively, the present compositions may comprise at least about 0.5% total fermentable fiber, at least about 1% total fermentable fiber, at least about 2% total fermentable fiber, alternatively from about 1% to about 20% total fermentable fiber, alternatively from about 1% to about 10% total fermentable fiber, alternatively from about 2% to about 10% total fermentable fiber, or alternatively from about 3% to about 8% total fermentable fiber, all by weight of the pet food composition.

In one embodiment herein, the compositions may comprise a nutraceutical. Nutraceutical as used herein means a foodstuff (as a fortified food or dietary supplement) that provides health benefits.

Additional material that can be present in the composition of the present invention include minerals such as but not limited to Calcium Carbonate, Calcium, Boron, Selenium, Calcium Chloride, Chloride, Ferrous Fumarate, Zinc Acetate, Choline Chloride, Chromium, Ferrous Gluconate, Zinc Sulfate, Chromium, Tripicolinate, Cobalt, Magnesium Oxide, Zinc Gluconate, Dicalcium Phosphate, Copper, Magnesium Sulfate, Ferrous Sulfate, Iodine, Magnesium Carbonate, Monosodium Phosphate, Iron, Chromium Picolinate, Potassium Chloride, Magnesium, Calcium Citrate, Potassium Citrate, Manganese, Calcium Lactate, Potassium Sorbate, Phosphorus, Calcium Gluconate, Sodium Bisulfate, Potassium, Chromium Chloride, Sodium Hexametaphosphate, Sodium, Chromium Nicotinate, Tricalcium Phosphate, Zinc, Chromium Citrate, Yeast containing any of these minerals and the like.

Compositions of embodiments of the present invention may also comprise a prebiotic component. “Prebiotic” includes substances or compounds that are fermented by the intestinal flora of the pet and hence promote the growth or development of lactic acid bacteria in the gastro-intestinal tract of the pet at the expense of pathogenic bacteria. The result of this fermentation can be a release of fatty acids, in particular short-chain fatty acids in the colon. This release can have the effect of reducing the pH value in the colon. Non-limiting examples of suitable prebiotics include oligosaccharides, such as inulin and its hydrolysis products commonly known as fructooligosaccharides, galacto-oligosaccarides, xylo-oligosaccharides, or oligo derivatives of starch. The prebiotics may be provided in any suitable form. For example, the prebiotic may be provided in the form of plant material that contains the fiber. Suitable plant materials include asparagus, artichokes, onions, wheat or chicory, or residues of these plant materials. Alternatively, the prebiotic fiber may be provided as an inulin extract, for example extracts from chicory are suitable. Suitable inulin extracts may be obtained from Orafti SA of Tirlemont 3300, Belgium under the trade mark “Raftiline”. For example, the inulin may be provided in the form of Raftiline (g) ST which is a fine white powder, which contains about 90 to about 94% by weight of inulin, up to about 4% by weight of glucose and fructose, and about 4 to 9% by weight of sucrose. Alternatively, the fiber may be in the form of a fructooligosaccharide such as obtained from Orafti SA of Tirlemont 3300, Belgium under the trade mark “Raftilose”. For example, the inulin may be provided in the form of Raftilose (g) P95. Otherwise, the fructooligosaccharides may be obtained by hydrolyzing inulin, by enzymatic methods, or by using micro-organisms.

The compositions herein may comprise any of a variety of components that are sensitive to process conditions ordinarily attendant with manufacture of a pet food. For example, the integrity of such sensitive components may be preserved (either fully or partially). Non-limiting examples of sensitive components include components that exhibit more than about 10% loss (by weight) during standard extrusion processes when included within a standard, commercial pet food, alternatively more than about 20% loss, alternatively more than about 50% loss. Extrusion processes are well-known in the art. Included or alternative examples of sensitive components including antioxidants such as vitamins including but not limited to vitamin A (including forms thereof, such as beta-carotene and lycopenes), vitamin C (including forms thereof), vitamin E (including forms thereof), vitamin D (including forms thereof), Phenols, Carotenoids, Alkaloids, xanthones, polyphenols, beta-carotene, organosulfur, curcumin, kaempherol, astaxanthin, gamma-glutamylcysteines, catechins, pterostilbene, canthaxanthin, cysteine sulfoxides, ellagic acid, quercetin, tunaxanthin, isothiocyanates, baicalin, tocopherols, myricetin, zeaxanthin, flavonoids, resveratrol, anthocyanins, bixin, isoflavonoids, vinpocetine, flavonols, lutein, Co-Q10, proanthocyanidins, lycopene, lipoic Acid and the like.

One embodiment of a process for making a pet food supplement in accordance with the compositions disclosed above is described hereinafter and is generally referred to in FIG. 1. FIG. 1 depicts a schematic of a process flow 10, which generally shows one embodiment of a process of making a pet food supplement. In this embodiment, the composition of the supplement can comprise cocoa butter, sweetener in the form of a white coating, one embodiment of which is described hereinabove, and a probiotic component in the form of probiotic microorganisms. Initially, cocoa butter can be heated up to around 130° F. and melted in cocoa butter tank 101, which can be a tank with jacket 102 connected to a heat exchanger 103. This heating can be done at least eight hours, or even longer, prior production of the final pet food supplement. Heating at least eight hours or more prior to production helps to remove residual water from the cocoa butter. Jacket 102 can have circulating warm water used to heat up the cocoa butter product in the tank 101. After heating and melting, the heated cocoa butter can then be transported through heat exchanger 103 to cool down the cocoa butter to around 110° F. This cool down to 110 from 130° F. helps to reduce inactivation of the probiotic microorganisms by the heat of the cocoa butter. Heating to 130° F. can assist in removing moisture from the cocoa butter, which can prevent premature activation of the probiotics microorganisms. However, 130° F. can be too high for the probiotics microorganism because it can deactivate the probiotic microorganism. At 110° F., deactivation of the probiotic microorganisms will generally not occur, and this temperature allows for a flowable and mixable cocoa butter component. From the heat exchanger 103, the cocoa butter can be transported by means of positive displacement pump 104 through flow meter 105 into mix tank 108. Flow meter 105 helps to control the proper amount of cocoa butter being transported by positive displacement pump 104. Screw pump 106 can be connected to mix tank 108 through flow meter 107. Screw pump 106 doses the quantity of probiotic microorganism into mix tank 108. Flow meter 107 helps to control the proper amount of probiotic microorganism into mix tank 108. The probiotic microorganism can be stored in a jar, bottle, or other container and added to a hopper, which can be connected with the screw pump 106. Mix tank 108 can be a jacketed scrape surface mix tank. This tank can be maintained at around 105° F. with warm water through jacket 109. At 105° F., rather than at 110° F., the probiotics microorganisms can be stored and kept for longer periods of time. Thus, operating at 105° F. at this point assists to prevent or inhibit any premature inactivation of the probiotic microorganisms. Mix tank 108 can be the location of the mixing of the probiotic microorganisms and the heated and melted cocoa butter.

Upon mixing of the cocoa butter and probiotic microorganisms, the mixture can be transported from the mix tank 108 through pump 110 into mix tank 117. Pump 110 can be a Moyno pump. A Moyno pump can allow for very gentle transportation of the mixture and thus can prevent or inhibit shear, damage, or other physical stress to the mixture and can be used for circulating the cocoa butter and probiotic microorganism mixture over mix tank 108. Static mixer 111 and three-way valve 112 work together to promote thorough mixing of the cocoa butter and probiotic microorganism mixture depending on the position of three-way valve 112. Three-way valve 112 can direct the mixture either back into mix tank 108 or into mix tank 117. Clumping of the cocoa butter and microorganism mixture should be avoided, and thus static mixer 111 and three-way valve 112 work together to reduce and attempt to eliminate clumping of the cocoa butter and probiotic microorganism mixture.

Once the mixture is mostly, if not completely, homogeneous and the probiotic microorganisms are saturated or fully coated with the cocoa butter, three-way valve 112 can be changed to a position to direct the mixture flow from mix tank 108 into mix tank 117. At this point, however, mix tank 117 can already contain the proper amount of white coating, or sweetener component, and transfer of the mixture of cocoa butter and probiotic microorganism from mix tank 108 to mix tank 117 should not commence until so, in one embodiment. The sweetener, or white coating, can be pulled from white coating tank 113. White coating tank 113 can have a jacket 114, which can assist in maintaining the tank at 105° F. The white coating can be held at 105° F. for around 24 hours or more prior to mixing it with the cocoa butter and probiotic microorganism mixture. White coating tank 113 can hold for storage the white coating and can keep it in melted form for mixing with the cocoa butter and probiotic microorganism mixture. The white coating can be pulled from white coating tank 113 by means of positive displacement pump 115, which can be controlled by flow meter 116 for the correct dosing amount. It has been found that for consistency purposes and for a better end product that it can be advantageous to mix the cocoa butter and probiotic microorganism mixture into the white coating in mix tank 117. Mix tank 117 can have a jacket 118 and can be a scrape surface mix tank. Mix tank 117 can be maintained at around 100 to 105° F. with warm water flowing through the jacket 118.

A Moyno pump 119 can be included and can be used to circulate the cocoa butter and probiotic microorganism mixture with the white coating over mix tank 117 to create a combined mixture. Static mixer 120 can be used to promote thorough mixing of the cocoa butter and probiotic microorganism mixture with the white coating and can be dependent on the position of three-way valve 121.

Once the combined mixture is fully, or sufficiently, homogenous, three-way valve 121 can be switched to a position such that the combined mixture can be transported by Moyno pump 119 away from the mix tank 117 to other equipment that can be used to form the combined mixture into supplement form.

If so desired, colorant can be dosed into mix tank 117 by means of dosing colorant from mix tank 122 by means of positive displacement pump, which can be controlled by flow meter. An all-natural colorant can be used. One non-limiting example of a colorant is CSL 37542 Brown Dispersion OB, available from Sensient Colors of St. Louis, Mo. It can also include caramel and paprika. However, it should be understood than any fat soluble colorant can be used, natural or non-natural. As non-limiting examples, the compositions herein may comprise about 0.1%, about 0.2%, about 0.3%, about 0.4%, or about 0% to about 1% colorant, all by weight of the composition.

It should be understood that a conditioned room 125 that is shaded in FIG. 1 can control the temperature and relative humidity of the screw pump 106, the flow meter 107, the mix tank 108, the pump 110, the mixer 111, and the three-way valve 112. Control can be done by arranging all of these items in a conditioned room or chamber. Control of temperature and relative humidity can assist in preventing premature activation of the probiotic microorganism. In at least one embodiment, the conditioned room 125 can be at around 100° F. and at a relative humidity of about 10% or lower. Once the probiotic microorganisms are coated with the cocoa butter, the risk of pre-mature activation of the probiotic microorganism can be dramatically reduced by use of a conditioned room. The conditioned room 125 can also prevent condensation from forming on the probiotic component.

Homogenous mixing of the probiotic microorganisms in the cocoa butter and with the white coating can be one embodiment. In some instances, problems arise with proper disbursement of the probiotic microorganisms and the cocoa butter throughout the white coating to form the combined mixture. At least one of those problems is the probiotic microorganisms not being disbursed in a relatively homogenous fashion throughout the combined mixture. This combined mixture, as described above, is the probiotic microorganisms and cocoa butter mixture combined with the white coating. This problem can arise when increased counts of probiotic microorganisms are used. Specifically, this problem can arise at levels such as 10¹⁰ CFU of the probiotic microorganisms. One way of addressing this problem associated with proper disbursement of the probiotic microorganisms in a homogenous fashion throughout the white coating mixture can be to create a two phase process of mixing the white coating with the probiotic microorganisms and cocoa butter mixture. FIG. 2 is a schematic showing one embodiment of a mixing process 20 than can be used. In this embodiment, the composition of the supplement can comprise cocoa butter, sweetener in the form of a white coating, one embodiment of which is described hereinabove as available from Blommer, and a probiotic component in the form of probiotic microorganisms. As before, initially the cocoa butter can heated up to around 130° F. and melted in a cocoa butter tank 201. This heating can be done at least eight hours, or even longer, prior production of the final pet food supplement. Heating at least eight hours or more prior to production helps to remove residual water from the cocoa butter. After heating and melting, the heated cocoa butter can then be transported and cooled down to around 110° F., or 105° F., or even lower. This cool down to 110 or 105° F. from 130° F. helps to reduce inactivation of the probiotic microorganisms by the heat of the cocoa butter. The cocoa butter can be transported into a mix tank 203. At this point, the appropriate quantity of probiotic microorganism from tank 202 can be dosed into the mix tank 203 to be mixed with the cocoa butter. The probiotic microorganism can be variable in granule size. It can range from dusty to particles that can be up to 2 or 3 mm in diameter. The probiotic microorganism can be derived from a fermentation culturing process where a starter organism is added to a nutrient rich growth media in a liquid (aqua) based environment. After the bacteria mix has grown through the log phase of growth (rapid bacterial growth), the bacterial mix is dried down through a spray drying process. It can then be stored at −4° C. or less. This mix tank 203 can be maintained at around 105° F. Thus, the mix tank 203 can be the location of the mixing of the probiotic microorganisms and the heated and melted cocoa butter.

At this point, the mixture of the cocoa butter and probiotic microorganisms can be combined with the white coating to assist in proper disbursement of the probiotic microorganisms. Such a combination can occur in mix tank 203. As before, clumping of the cocoa butter and microorganism mixture should be avoided, especially prior to addition of the white coating. Thus, mixing of the probiotic microorganisms and cocoa butter can be done for about five minutes until a smooth or mostly smooth mixture is attained. Once the mixture of probiotic microorganisms and cocoa butter is without or mostly without clumps, is mostly, if not completely, homogeneous, and the probiotic microorganisms are saturated or fully coated with the cocoa butter, a first addition of the white coating can be added to the mixture. This first addition of the white can comprise only a portion of the total amount of white coating that will eventually be added to the entire mixture. Again, this first addition can assist in proper disbursement of the probiotic microorganisms in the final combined mixture. In one embodiment, only about 30% of the total white coating is added to the probiotic microorganisms and cocoa butter mixture in this first addition. As before, the white coating can be pulled from a white coating tank 204. The white coating tank 204 can be maintained in the white coating tank at about 105° F. and can be held at this temperature for around 24 hours or more prior to mixing it with the cocoa butter and probiotic microorganism mixture. The mixing that occurs with this first addition of the white coating can occur in mix tank 203. Again, as before, it should be understood that a conditioned room 205 that is shaded in FIG. 2 can control the temperature and relative humidity of at least the mix tank 203. Control can be done by arranging all of these items in a conditioned room or chamber. Control of temperature and relative humidity can assist in preventing premature activation of the probiotic microorganism. In at least one embodiment, the conditioned room 125 can be at around 100° F. and at a relative humidity of about 10% or lower. Once the probiotic microorganisms are coated with the cocoa butter, the risk of pre-mature activation of the probiotic microorganism can be dramatically reduced by use of a conditioned room.

Upon addition of the first addition of the white coating to the mix tank 203 and mixing of the combined mixture of probiotics microorganisms, cocoa butter, and white coating, a second amount of white coating can be mixed with the combined mixture. Such mixing can occur in mix tank 206. At this point, however, mix tank 206 can already contain the rest of the white coating so that the cocoa butter, probiotic microorganisms, and first addition white coating can be added to the mix tank 206, which can already contain the white coating. In one embodiment where about 30% of the white coating was used a first addition, as above, the leftover about 70% can be used. The white coating can be pulled from white coating tank 204 into mix tank 206 prior to addition of the cocoa butter, probiotic microorganisms, and first addition white coating mixture. Again, the white coating tank 204 can be maintained at about 105° F. The white coating can be held at about 105° F. for around 24 hours or more prior to mixing. White coating tank 204 can hold for storage the white coating and can keep it in melted form for mixing. It has been found that for consistency purposes and for a better end product that it can be advantageous to mix the cocoa butter, probiotic microorganism mixture, and first addition white coating into the white coating in mix tank 206. Mix tank 206 can be maintained at around 100 to 105° F. A pump can be included and can be used to circulate the cocoa butter, probiotic microorganism, and first addition white coating mixture with the white coating over mix tank 206 to create a combined mixture. The combined mixture can be sent to mix tank 207 and mixed with a colorant, as above, which can be added from tank 208 into the mixture. To assure sufficient mixing of all of the components, one embodiment can include mixing of the components for at least about 20 minutes to form a homogenous mixture. At this point, the mixture can have melting properties such that it is a complete crystalline solid at 0° C., begins crystallizing at 18° C., and begins melting at 25° C., and is in a complete liquid phase at 39° C.

Upon a sufficiently homogenous mixture of the cocoa butter, probiotic microorganism, white coating, and colorant, if any, the combined mixture can be sent to further processing equipment for making into the desired form of the pet food supplement. In one embodiment, the mixture can be deposited into blister pack trays as part of the overall process. In this embodiment, the blister pack trays comprise any number of thermoformed blister enclosures that can function and can serve as molds for the mixture. The blister pack tray and the enclosures, as described in more detail hereinafter, can comprise any number of shapes, sizes, and configurations to serve any number of functions in completing the pet food supplement manufacturing process and in delivering the pet food supplement to a consumer. As mentioned above, the mixture can be deposited into the thermoformed blister enclosure, which functions as a mold for the mixture. The temperature of the mixture during depositing into the blister enclosure can be around 100° F. The blister pack, enclosure, and deposited mixture then can go through a cooling process that allows the mixture to harden in the enclosure. The cooling process can occur through a cooling tunnel, for example, and can occur at around 60° F. for about seven to twelve minutes. Of course, cooling can be completed at other temperatures and times, and such temperatures and times are dependent on one another. For example, cooling can be done at around 50° F., or even below 50° F., for around five to ten minutes. During this cooling, the mixture will harden and crystallize while in the enclosure mold to form a solid supplement. If the enclosure mold comprises a specific shape, the mixture can harden into that shape. Non-limiting examples of such shapes and forms include round, oval, rectangular, square, triangular, trapezoidal, octagonal, bone, heart, and steak, and are described in further detail hereinafter. After cooling, the enclosure can be sealed with a closure, such as a foil closure that can be rupturable by a consumer using nominal force. Sealing of the closure, with foil, can be completed at the appropriate temperature and dwell time based on the type of material used for the foil and blister pack. At this point, a blister pack with blister enclosures filled with pet food supplements has been manufactured. Once sealed, the blister pack can then be inserted into a secondary container or package, the configuration of which is described hereinafter in more detail.

The above processing allows extremely consistent and controllable dosing through the supplement. By sufficient and homogenous mixing of the multiple components, a controllable amount of probiotic component can be provided in a single supplement and results in an end product that is consistent, reliable, and dependable in providing a dose of a probiotic component in a supplement.

Another suitable process for the preparation of pet food compositions can be at least partial extrusion, although baking and other suitable processes may be used. When extruded, the dried pet food is usually provided in the form of a kibble. A process is described in EP 0,850,569.

Generally, the packaging for the pet food supplement of embodiments of the present invention can comprise a primary container, the primary container having at least one enclosure, the enclosure containing at least one dosage unit or supplement, and the dosage unit or supplement comprising a probiotic supplement. The primary container can be a blister pack, as referred to hereinabove, blister card, or blister sheet as would be understood and commonly used in the art. The primary container can be of varying shape and size as desired based upon the number, size, and type of supplement contained therein and can be sized to be conveniently portable. Non-limiting examples of such shapes include round, oval, rectangular, square, triangular, trapezoidal, hexagonal, octagonal, paw print, and combinations thereof. The shapes can include other indicia, such as trademarks, brand names, trade dress features, and the like. For example, a paw print can be used, as shown in FIG. 3. The paw print can be embossed or debossed. The primary container can also be formed to have means to permit separation of one or more portions of the primary container, i.e. one or more portions containing an enclosure. As would be understood by those of skill in the art, non-limiting examples of such means include perforations, scoring and combinations thereof.

As would be understood by those skilled in the packaging arts, to include structure and making of packaging, a blister pack can include one or more blister layers and a rupturable layer, the combination of which encloses one or more supplements. Thus, the blister layer can provide enclosures, in any suitable size and/or shape, for one or more supplements of any suitable size, shape, or form.

The paw print can be embossed or debossed. The rupturable layer permits the supplement to be removed from the blister pack. The rupturable layer can be formed over all or a portion of the blister layer. The rupturable layer can be affixed to the blister layer via the application of heat and pressure as is common in the art using conventional thermal forming methods, or by adhesive. Such blister packs can also comprise a backing layer that can be disposed on or over the rupturable layer to prevent unintended rupture and release of dosage units. Such backing layer can be peeled away to expose the rupturable layer when release of a supplement is desired. Such backing layer can be formed over all or a portion of the rupturable layer. Such a backing layer can be affixed to the rupturable layer and/or the blister layer via, for example, adhesive.

Blister layers can be made from a variety of suitable materials, non-limiting examples of which include polyvinyl chloride, thermoplastic materials, polyolefins and combinations thereof. The blister layer can be opaque, partially opaque, or transparent, and can be colorless or colored.

Rupturable layers can be made from a variety of suitable materials, non-limiting examples of which include metal foil, tempered metal foil, paperboard, polyvinyl chloride, polyolefins, polystyrenes, polyesters, fluoropolymer resins, and combinations thereof. The rupturable layer can also be formed as a laminate composed of a plurality of laminated layers of different materials, so long as its basic operation and rupturability is not affected. The rupturable layer can be of any desired color.

Backing layers can be made from a variety of suitable materials, non-limiting examples of which include paper, plastic, polyvinyl chloride, and combinations thereof. The backing layer can be of any desired color.

An example of one embodiment of a primary container is depicted in FIG. 3. Blister pack 30 can contain individual blister enclosures 31 and blister layer 33. Blister pack 30 can include one or more blister layers 33 and a rupturable layer (not shown), the combination of which encloses one or more pet food supplements. Thus, the blister pack of FIG. 3 comprises at least one enclosure 31, the enclosure containing at least one pet food supplement 32, the pet food supplement comprising a probiotic component. The rupturable layer can permit the supplement to be removed from the enclosure and thus the blister pack.

A cross section of an enclosure of one embodiment of the present invention is depicted in FIG. 3A. Enclosure 31, as shown, can be a hexagon. However, it should be understood that enclosure 31 can be made into any shape, and it can be symmetrical, as shown in FIG. 3A, or asymmetrical. Enclosure 31 can include lips 34 a and 34 b that form part of the blister layer 33 of FIG. 3. Lip 34 a can then end at surface 35, which begins to form the surface of the enclosure 31. Surface 35 can extend outwards from the interior of the enclosure 31 and then inward towards the interior of the enclosure, forming surface 36, forming a slight v-shape. Surface 36 can then extend downward and lessen its angle with the vertical, forming body surface 37. Body surface 37 can form the main body of the supplement. Body surface 37 can then continue downward and end at bottom surface 38. Bottom surface 38 can form the top of the supplement and thus feature surface 39 can be used to include indicia and/or be made into a shape, such as a paw print, to the top of the supplement. Of course, feature surface 39 can be of any shape or size, as is described herein. In this configuration, the bottom surface 38 and the body surface 37 define an interior volume for the supplement.

Fill line 40 can represent the height of a mixture or a finished supplement when filled or hardened in the enclosure 31. Not wishing to be bound by theory, it can be advantageous for the finished supplement to fill the enclosure to fill line 40. In one embodiment, the mixture that forms the supplement can be filled into enclosure 31. Once filled, it can harden while in the enclosure, and thus can take the shape of the enclosure. Upon hardening, a tight fit is not always achieved between the supplement and the enclosure walls. In other words, as the supplement has hardened, it does not always stay tightly fit into enclosure 31. Some shrinkage can occur, some disturbance of the containers can occur, among other things, all of which can jostle the supplement from its original fit into the enclosure 31. Thus, if the supplement is jostled such that it is no longer tight fitting within the enclosure, it can have a tendency to move around within the enclosure 31. Thus, surfaces 35 and 36 can together define a frill that can be useful for preventing negative consequences due to the movement or jostling of the supplement. For example since the frill formed by surfaces 35 and 36 can form a v-shape, and the top of the supplement is at or around fill line 40, surface 35 of the frill can have a top position that can be inside of the outermost surface of the supplement, which can be at the transition between surface 35 and surface 36. In other words, the largest radius of the enclosure, or the supplement when deposited and hardened in the enclosure, which is formed by the transition between surface 35 and surface 36, is greater than the radius at the fill line 40. Thus, surface 35 can act as a stopper to prevent the supplement from falling out of the enclosure 31. Such a feature can be extremely advantageous when enclosures are used as both a mold and a holding/shipping/delivery vehicle.

Feature surface 39, as mentioned above, can include any indicia and/or be made into a shape. As shown, feature surface 39, when formed into a shape, can form a surface exterior to that of bottom surface 38. When enclosure 31 is an enclosure as part of a blister pack, feature surface 39 can serve many purposes. For example, when feature surface 39 forms a surface exterior to that of bottom surface 38, it can allow a consumer an easier way to push out the supplement out of the enclosure and through any seal that can be present. Surface feature 39 can also depict a shape or indicia that can be correlated to a certain type of benefit provided, to a certain brand, or to certain ingredients of the supplement, as is described herein. Thus, this surface feature 39 can be an easy identifier to a consumer if the blister pack 30 is somehow separated from its secondary container that includes indicia identifying the type of supplement contained therein.

Furthermore, the frill formed by surfaces 35 and 36 can allow for removal of the supplement without deformation. Such removal can be achieved by maintaining a radius geometry in the frill and a minimum depth of the frill. Also, the inclusion of a draft angle of the frill of approximately 5 degrees facilitates ease of dispensing without product deformation.

The packaging for the pet food supplement of embodiments of the present invention can also optionally include a secondary container. A secondary container can contain one or more separate, discrete primary containers and/or can be formed as an integrated structure with the primary container. The secondary container can be of varying shape, size and form as desired based upon the number, size and type of primary containers contained therein and/or formed as a part thereof, and can be sized to be conveniently portable. Non-limiting examples of such shapes and forms include round, oval, rectangular, square, triangular, trapezoidal, octagonal, foldable and combinations thereof. Non-limiting examples of secondary containers include boxes and cartons. Non-limiting examples of integrated primary and secondary containers include tri-fold structures in which a primary container is affixed to a secondary container that folds over one or more portions of the primary container; and structures shaped and structured similarly to a book in which one or more primary structures form page-like structures bound within a secondary container outer covering forming an integrated structure. The primary and secondary containers can also be separate, discrete elements, and one or more primary containers can be removed from the secondary container. The secondary container can be made from a variety of materials, non-limiting examples of which include paper, paperboard, cardboard, plastic, and combinations thereof. FIG. 4 depicts one embodiment of a secondary container and a primary container. Secondary container 40 can be a carton or box. Primary container 30 can be a blister pack, as shown in FIG. 3 and as shown contained within carton 40 in FIG. 4. In this embodiment, the secondary container 40 also includes indicia 41, which can aid in directing a consumer or a veterinarian in the selection of an appropriate supplement. In this embodiment, the indicia are text. Other non-limited examples of indicia are shapes, objects, pictures, brand names, words associated with benefits, etc. Particular indicia are described hereinafter. Secondary container 40 can also comprise a viewing aperture 42. Viewing aperture 42 can permit viewing of a portion of primary container 30 therethrough. As shown in the embodiment of FIG. 4, the supplement 32 of FIG. 3 can be viewable through the viewing aperture 42. The depth 43 of primary container 40 can influence the distance that the supplement protrudes through the viewing aperture 42. For example, it depth 43 is sufficiently deep such that it is greater than the height of a supplement, the supplement will not protrude through the viewing aperture. However, if the depth is less than the height of the supplement, the supplement, or at least a portion of the primary container, will protrude through the viewing aperture. In addition, secondary container 40 can have an indentation 44 that can be utilized by a consumer to aid in removal of primary container 30 from secondary container 40.

As described above and as is shown in FIG. 4, the secondary container can also provide one or more viewing apertures, such as viewing aperture 42, that can be an uncovered void in the secondary container or can be a void covered by a material, non-limiting examples of which include transparent plastic materials. A viewing aperture 42 can be used to allow viewing of one of the products in the primary container, and, as described above, it can allow the supplement to protrude therethrough.

The secondary container can also aid in the storage, transport, distribution, display, and/or sale of the primary container and the supplement contained therein.

As also described above and as is shown in FIG. 4, the secondary container can also comprise one or more receiving portions to aid in handling of the primary and/or secondary container, such as indentation 44. Non-limiting examples of such receiving portions include one or more indentations in the secondary container to allow access to and gripping of a primary container to permit removal of the primary container from the secondary container.

Such a combination of primary container and secondary container can comprise an easy to dispense unit dosage of a supplement. Such a combination can be beneficial for a supplement comprising a probiotic component. The further combination of product form as a supplement and the primary container and secondary container also promotes and encourages compliance. For example, a probiotic supplement can have a regime associated with it such that a beneficial dosage amount can be one supplement per day. Such a dosage amount should be easily administrable by a consumer. It has been found that the combination of a supplement in a primary container within a secondary container promotes such a regime. Thus, this combination encourages and promotes regiment compliance via an easy to use dosage form.

The primary container and/or the secondary container and/or the supplements themselves can also comprise indicia, which indicia can enable a user to identify the appropriate package and/or appropriate supplement to select based on the consumer's needs for its pet. Thus, the indicia can communicate with the consumer to identify the appropriate treatment and use thereof.

The supplements can be arranged in the primary container in any number of ways, depending on the system and the desired treatment and/or benefit. For example, a primary container can comprise multiple groups of supplements arranged in multiple rows and/or columns of supplements, each supplement of a particular row or column can be the same type of supplement with each particular row or column of supplements comprising a different probiotic component, or the same probiotic component, for providing particular health benefits, as mentioned above. Thus, in one embodiment, a blister pack as a primary container can have three rows or columns, and the first row can comprise a probiotic component associated with a first health benefit, the second row can comprise a probiotic component associated with a second health benefit, and the third row can comprise a probiotic component associated with a third health benefit. Any number of rows or columns can be used, and any number of probiotic components and associated health benefits can be used. Each particular row of probiotic can comprise a particular shape, particular indicia, and/or particular colors that can be associated with particular health benefits. Thus, a form of multi-pack of supplements for multiple health benefits can be embodied.

Moreover, color can be utilized to indicate the health benefit provided by a supplement. A color can be associated with a certain health benefit provided. For example, green can be used to indicate a gastrointestinal benefit that can provided by a supplement. Green can be used as indicia on the primary container and/or on the secondary container. Any color can be used, and any color can be matched with a specific health benefit. The color can be used as indicia in any kind of form. For example, the color can be a stripe, or multiple stripes, going across any portion of the secondary or primary container. The color can be in the form of other shapes, stripes, outlines of the containers. Colors can be used in an array, as is described in more detail below. More than one color can be used to indicate more than one benefit being provided. Furthermore, other certain indicia can be used, particularly consumer conscious indicia. Consumer conscious indicia can include, for example, a picture, or outline, of a companion animal, such as a dog, as shown in FIG. 5. A picture or outline of a dog 50 can include any variation of the breeds of dogs and is not limited in any way by the outline shown in FIG. 5. In FIG. 5, other indicia can be included to form consumer conscious indicia. As non-limiting examples, the outline of the dog 50 can include target areas. Target areas can be areas or body parts of the dog that are highlighted, pointed to, or emphasized in any way and can signal the area of the dog, or other companion animal, that the type of health benefit that is being provided by the supplement. For example, target area 51 can generally be located in or around the gastrointestinal tract of the dog. The location can then signify to a consumer that the supplement contained within that secondary container can be a supplement that is for treating the gastrointestinal health of the dog. Other non-limiting areas of the dog that can be used, for example, would include skin and coat shown by 52, eye health shown by 53, diarrheal, and all other areas or body parts of the dog or companion animal that can be represented by health benefits that a supplement can treat. Such health benefits have been identified above. Moreover, the actual target can be exemplified by any indicia. Non-limiting examples include trademarks, logos, stars, targets, highlighting, colors, etc. For example, a trademark can be used at the point of treatment, such as a paw print on the gastrointestinal tract. Of course, any animal can be used. Combinations of indicia can also be included such that, for example, a secondary package can have green indicia, a dog can have a target area located around the intestinal tract, a particularly shaped hexagon supplement can be shown in the viewing aperture, and a “GI” text can be used on the secondary container for easy viewing, and this combinations of indicia all can represent a particular pet food supplement for treating the gastrointestinal tract of the dog. Of course, any combination of these indicia can be used for a specific health benefit and can be used in combination with any of the other packaging aspects and supplement forms.

A color sleeve or meter can also be included. For example, any secondary container containing a supplement sold by a specific company can include a color meter. Such a color meter can include an identification of all of the health benefits and their associated color indicia used on the primary or secondary containers. In a non-limiting example shown in FIG. 6, a color meter 60 can be rectangular, or any other shape, and can have color strips 61-68. Color strips 61-68 can be an actual color. Color strips 61-68 can be labeled in any fashion with a health benefit that is associated with that color. Such a color strip can be included on all containers such that a consumer can be informed, or communicated with, of the supplement offerings for particular health benefits of a particular company and can then best locate the particular supplement and health benefit easily by using color.

The supplement itself can be of any various colors. Such color can again be used to indicate the type of health benefit being provided, as above. In one embodiment, the supplement can be generally beige or brown in color. In other embodiments, the supplement can be of any color. The colors, as above, can be indicative of the health benefit. It is also envisioned that supplements can comprise multiple probiotic components such that a single supplement provides multiple health benefits. In such a case, the supplement can be any color, or it could be a marbling of colors. Such a marbling of colors can indicate multiple health benefits since multiple colors are present.

The colors can be represented by the Hunter Lab color space. As is well known in the art, the Hunter values are a measure of reflected light and use three parameters: L, a, and b. Generally, “L” denotes the level of white/black, or lightness, and the “a” and “b” values are termed the opponent color axes. The “a” opponent color axis represents, approximately, the redness or greenness (positive or negative) while the “b” opponent color axis represents the yellowness or blueness (positive or negative). The color white can be represented by an “L” value of 100 while the color black is represented by an “L” value of 0. The color gray can be represented by “L” values between 0 and 100 at a and b values of zero. The color red can be represented by a positive “a” value while the color green can be represented by a negative “a” value. The color yellow can be represented by a positive “b” value while the color blue can be represented by a negative “b” value. All values included and therebetween for each of the colors associated with the Hunter values are within the scope of the embodiments of this invention and can be represented as red, green, blue, yellow, purple, tan, brown, beige, black, white, gray, orange, pink, lavender, pink and combinations and mixtures thereof based on their particular Hunter Lab values.

Many test methods for measuring the Hunter Lab color and its associated values are well known in the color art. Any of those test methods can be used within embodiments of the present invention. One non-limiting example of a test method is disclosed hereinafter.

Color-containing surfaces are tested in a dry state and at an ambient humidity of approximately 500%.±0.2%. Reflectance color is measured using the Hunter Lab LabScan XE reflectance spectrophotometer obtained from Hunter Associates Laboratory of Reston, Va. The spectrophotometer is set to the CIELab color scale and with a D50 illumination. The Observer is set at 10°. The Mode is set at 45/0°. Area View is set to 0.125″. Port Size is set to 0.20″ for films. Area View is set to 1.00″, and Port Size is set to 1.20″ other materials. The spectrophotometer is calibrated prior to sample analysis utilizing the black and white reference tiles supplied from the vendor with the instrument. Calibration is done according to the manufacturer's instructions as set forth in LabScan XE User's Manual, Manual Version 1.1, August 2001, A60-1010-862.

If cleaning is required of the reference tiles or samples, only tissues that do not contain embossing, lotion, or brighteners should be used (e.g., Puffs® tissue). Any sample point on the externally visible surface of the element containing the imparted color to be analyzed should be selected. Sample points are selected so as to be close in perceived color. A sample of the material being tested is placed over the spectrophotometer's sample port. The sample comprising the color to be analyzed must be larger than the sample port to ensure accurate measurements. A white tile, as supplied by the manufacturer, is placed behind the externally visible surface. The L*, a*, and b* values are read and recorded. The externally visible surface is removed and repositioned so that a minimum of six readings are obtained for the externally visible surface. If possible (e.g., the size of the imparted color on the element in question does not limit the ability to have six discretely different, non-overlapping sample points), each of the readings is to be performed at a substantially different region on the externally visible surface so that no two sample points overlap. If the size of the imparted color region requires overlapping of sample points, only six samples should be taken with the sample points selected to minimize overlap between any two sample points. The readings are averaged to yield the reported L*, a*, and b* values for a specified color on an externally visible surface of an element.

It is also envisioned that the containers and products of the present invention can communicate with a consumer, as described above. Such communication can be intuitive. For example, after usage of a particular supplement, a consumer may relate a particularly shaped supplement with a particular health benefit. Moreover, a consumer may relate a particularly colored container or supplement with a particular health benefit. Any other indicia described above may be related by a consumer with a particular health benefit. Thus, at a point, the supplement and/or the containers may intuitively communicate with a consumer such that the consumer readily identifies the supplement and/or the container with a certain health benefit, and such identification by the consumer may be based on the indicia related to the container and/or supplement.

Embodiments of the present invention also include an array. An array of containers, either primary or secondary, can be arranged. An array of supplement containers can comprise, for example, a first container, such as either a primary or a secondary container, and a second container, such as either a primary or a secondary container. In a non-limiting example, a first container comprises a secondary container housing a primary container of supplements and a second container comprises a secondary container housing a primary container of supplements. The first container and the second container may comprise indicia, either textual or non-textual. The indicia may be associated with a health benefit that is provided by the supplement. The indicia may also include a color in the form of a stripe on the secondary container, whereby the color also is associated with a particular health benefit. Of course, multiple indicia can be used.

The array may comprise a third, a fourth, or any number of further containers. An array may comprise an entire lineup of offerings by a specific company for a specific product, such as a probiotic supplement. The further containers of the array may comprise indicia.

In some embodiments, a secondary container can contain a primary container, which can contain a single type of supplement, for example supplements for providing a first type of health benefit, such as increased mobility. Another primary container can comprise another single type of supplement, for example supplements for providing a second type of health benefit such as skin and coat health. The primary containers, the supplements, and/or the secondary container can comprise indicia, as described hereinabove, to enable a user to identify the appropriate health benefit being provided by the supplement, and thus select the appropriate supplement and use thereof. These containers can be arranged in an array, as described above, such that a mobility supplement and a skin and coat supplement can be provided on a store shelf, in a veterinarian's office, or in any display used to communicate the product. The health benefit can be any of those described hereinabove. Such an array of primary containers and/or secondary containers can further comprise indicia located on the primary container, as described hereinabove. A secondary container, which includes a primary container, can contain at least one, two, three, or any number of elements or forms of indicia on the package. In one non-limiting example, a secondary container, which includes a primary container, can contain at least three elements or forms of indicia on the container. Those three forms of indicia can be a picture or drawing of a dog, a supplement, such as in the form of a hexagon, and a brand name, such as Iams™. Other forms of indicia can be included and are described hereinabove.

It also envisioned that a single container, whether primary or secondary, can include different types of products, or supplements, such that a single container has a first supplement for providing a first health benefit and a second supplement for providing a second health benefit. Additional supplements can be included. A secondary container can also include a first primary container of supplements for providing a first health benefit and a second primary container for providing a second health benefit. Additional containers and supplements can be included.

Multi-packs of secondary containers can also be envisioned. A multi-pack may include one or more secondary containers, which may contain one or more primary containers, which may include one or more supplements, wherein the supplements can provide multiple health benefits. Thus, a multi-pack of containers may include several supplements for providing several health benefits. In such a scenario, a consumer could purchase one multi-pack that contains many supplements for providing many health benefits.

In addition to the supplement containers described hereinabove, marketing articles such as in-store ads, in-store flyers, print ads, periodical ads, billboards, end-of-aisle displays, pallet wrappers, additional packaging, corrugated boxes, floor ads, window stick-on ads, shelf talkers, internet sites, etc. associated with the supplement products may also comprise indicia. The indicia on the marketing articles may be matched to a health benefit provided by the supplement.

The present invention can also include kits that can comprise one or more systems of the present invention packaged in combination with complementary pet products, such as any type of product normally found in a pet supply store.

Other Forms of the Supplement

The final pet food supplement can take many forms of a pet food, such as a tablet, capsule, or the like, or other forms such as biscuits, chews, edible films or other treats, which are intended to be used not as entire pet meals but in addition to regularly consumed pet food meals.

Many known pet food compositions and supplements are available in a variety of forms and textures. Most of these pet food compositions tend to be inflexible, such as extruded pet food kibbles, compressed tablets, or gelatin capsules. Depending upon the intended use or function of the composition, inflexibility may be a property that is desirable or undesirable. For example, a product texture that is suitable to healthy pets, such as a kibble, provides the desirable advantage of enabling the pet to easily consume to provide the nutrients necessary to sustain life. However, for pets with oral disease, hard textures can pose an ergonomic challenge. In those instances, products such as a tablet, extruded, or baked compositions are harder to fracture during mastication due to tooth loss or health status. This problem is especially true for canines with brachycephalic skulls, such as boxers, pugs, etc., which are prone to oral and mastication issues. In this instance, a softer composition would result in better compliance and consumption unless the form is found to be unacceptable to the animal. Gelatin capsules are an example of a supplement that can provide less fracture force than a traditional extruded or baked composition, but the texture does not ensure compliance with all canines. Rinses, gels, and sauces can also provide broader appeal to dogs with oral issues, but they often require the consumer to mix or add the fluid to another substrate for consumption, or they must place the fluid on a secondary deliver vehicle such as a bowl, brush, etc. These further forms are contemplated as within the scope of embodiments of the present invention.

It can also be advantageous to provide pet food compositions/supplements with probiotic component benefits that can be delivered in a stand alone form that can be easily handled by the consumer for direct feeding to a pet. Similarly, little effort should be required by the pet to consume the product to achieve a benefit, regardless of life stage or health status. A non-limiting example of this embodiment can be the use of a fat based probiotic treat that is a solid at ambient temperature, and a liquid at the target animal body temperature. In that manner, the treat could be hand fed to a pet, but the form would provide a soft texture for the pet to chew making it suitable for all breeds and life stages. Additionally, if prolonged mastication were required, the treat would quickly liquefy in the animal's mouth to deliver the desired health benefit. This further form is contemplated as within the scope of embodiments of the present invention.

Still other forms of the supplement can be envisioned. In one embodiment, compressed tablets can be made. A compressed tablet can comprise any of the ingredients described hereinabove. In one process, the probiotic component can be combined with an excipient, non-limiting examples of which include fibers, other fillers, and pre-biotics. A binder can be included, non-limited examples of which include cellulose, methyl cellulose, polyvinyl pyrrolidone, and polyethylene glycol. This mixture can be put through a fluid bed rotor granulator, as is known to those of skill in the art. Upon drying, lubricants, non-limiting examples of which include talic, silica, and fats, and disentegrants, non-limiting examples of which include starch, cellulose, cross-linked polyvinyl pyrrolidone, sodium starch glycolate, sodium, and carboxymethyl cellulosemethycellulose can be added. Upon compression, coating can be done along with other standard procedures as known to those of ordinary skill in the art, including cooling, to form a tablet comprising a probiotic component.

Another form can be compressed tablets enrobed with a coating. The compressed tablet above can be made. However, an additional step can be included after compression such that a coating, such as the Blommer white kreemy coating component described hereinabove, can be used to enrobe the tablet. The resulting product is an enrobed compressed tablet comprising a probiotic component.

Another form can be lentils, which can be pan coated. Lentils can be made by using the cocoa butter, probiotic, and Blommer coating mixture, as hereinabove described. That mixture can be deposited onto rollers at around 10 degrees below 0° F., depending on the speed of the rollers. Pan coating can then be done at around 68° F. for about three hours using medium tumble. A 1 to 11 6× sugar and 1 to 70 gum mix can be added with additional pan coating at about 75 to 100° F. Drying can then be done at about 60 to 70° F. for at least 10 hours. The pan coater can then be run again, at about 100° F. for about 20 minutes, and 1 to 6.6 74% syrup mixed with a colorant can be added during the run. The pan coater can be run for an additional two minutes at around 85° F. while adding shellac with alcohol. A final lentil can then be formed

Another form can be lentils, which can be pan coated with a second high melting point layer. Lentils can be made by using the cocoa butter, probiotic, and Blommer coating mixture, as hereinabove described. That mixture can be deposited onto rollers at around 10 degrees below 0° F., depending on the speed of the rollers. The pan coater can then be run for about 30 minutes, and a 1 to 11 6× sugar and 1 to 70 gum mix can be added with additional pan coating at about 75 to 100° F. Drying can then be done at about 60 to 70° F. for at least 10 hours. At this point, it can be pan coated with a higher melting point fat. At least options can be chosen after pan coating with a higher melting point fat: 1) cool the lentils down for a final product; 2) run the pan coater for an additional amount of time at 85° F., which can be 2 minutes, with the addition of shellac with alcohol, and then cool down; or 3) run the pan coater for an additional amount of time at a temperature of about 100° F. while mixing in 1 to 6.6 74% syrup with a white colorant, followed by running the pan coater for an additional amount of time at 85° F., which can be 2 minutes, with the addition of shellac with alcohol, and then cool down.

With respect to the second high melting point layer lentil, two other options exist for processing before depositing on the rollers at around 10 degrees below 0° F.: 1) the mixture can be simply dropped on moving belt in the appropriate sized lentil followed by crystallizing and cooling, after which one can pan coat at approximately 68° F. for about three hours followed by any of the processing options above with respect to the pan coater; or 2) the mixture can be deposited into forms in cavity trays, then followed by crystallizing and cooling, then removed from the tray, and then one can pan coat at approximately 68° F. for about three hours followed by any of the processing options above with respect to the pan coater.

A seeding crystal can be included. A seeding crystal can be used to enable the product to be quickly re-formed into its solid form if melting or other means as caused the supplement to lose its desired hard form. A seeding crystal, as is well known in the art, comprises a small single crystal that can be placed into a saturated or supersaturated solution to grow a large crystal. In some embodiments of the present invention, a seeding crystal can assist in the crystallization of a supplement if it becomes a liquid due to high temperatures.

EXAMPLE

In one example, pet supplements or treats are to be made. Each supplement or treat will contain approximately 5×10¹⁰ CFU of probiotic microorganism. Each treat will weigh approximately 2.5 grams and have a composition of probiotic animalis at 10%, cocoa butter at 3.39%, Blommer white coating at 86.28%, and 37542 Brown Dispersion OB paprika colorant at 0.33%, by weight of the total composition. This composition is prepared as follows:

In a temperature and humidity controlled chamber of approximately 10% or less relative humidity and at 100° F., the cocoa butter is heated to about 130° F. and then cooled down to about 105° F. The cocoa butter and probiotic are mixed thoroughly in a mix tank until a dough-like consistency is reached. At this point, approximately 30% of the white coating, which has been in a tank outside of the controlled chamber and is has been held at about 105° F. for about 24 hours, is added to the cocoa butter and probiotic mixture. This combined mixture is thoroughly mixed for about five minutes or until a smooth consistency is reached. The remainder of the white coating is added to a separate mix tank. At this time, the combined mixture, which has been thoroughly mixed for about five minutes or until a smooth consistency is reached, is added to the remainder of the white coating in the separate mix tank. This mixture is then mixed thoroughly for about five minutes. At this time, the colorant is added to the mixture. This final mixture is mixed thoroughly for about 20 minutes, resulting in a supplement composition that is ready for addition to a mold for hardening and packaging.

What is claimed is:
 1. A pet supplement comprising a homogeneous mixture consisting of an amount of probiotic microorganisms and a first fat component having a first melting point; and a sweetener component comprising sugar and a second fat component having a second melting point; Wherein the second melting point is different than the first melting point and the supplement has a viable probiotic microorganism count of at least about 10⁵ colony forming units (CFUs) per gram of composition.
 2. The pet supplement of claim 1, wherein the supplement is molded.
 3. The pet supplement of claim 1, wherein the probiotic component comprises one or more yeast or bacterial microorganisms.
 4. The pet supplement of claim 3, wherein the probiotic component comprises a bacterial microorganism selected from the genera Bacillus, Bacteroides, Bifidobacterium, Enterococcus, Lactobacillus, Leuconostoc, or a combination thereof.
 5. The pet supplement of claim 1, comprising a viable probiotic microorganism count of at least about 10⁵ colony forming units per gram of composition.
 6. The pet supplement of claim 1, having a shelf life of from about six to about eighteen months.
 7. The pet supplement of claim 1, wherein the sweetener component comprises one or more mono- or disaccharides having a melting point of from 80° C. to 140° C.
 8. The pet supplement of claim 7, wherein the mono- or disaccharide consists of sorbitol, xylitol or a combination of these.
 9. The pet supplement of claim 1, wherein the first fat component comprises a cocoa butter component.
 10. The pet supplement of claim 9, wherein the cocoa butter component does not comprise a cocoa butter substitute.
 11. The pet supplement of claim 1, wherein neither the first or second fat component comprises an animal fat.
 12. The pet supplement of claim 1, further comprising one or more fermentable fibers.
 13. The pet supplement of claim 12, wherein the fermentable fibers are selected from beet pulp, fructooligosaccharide or a combination thereof.
 14. A method of making a pet supplement comprising mixing a first fat component having a first melting point with a probiotic component comprising an amount of probiotic organisms to provide a homogeneous mixture; mixing a sweetener component comprising sugar and a second fat component having a second melting point with the homogeneous mixture of probiotic component and fat component to provide a homogenous pet supplement mixture; and forming the pet supplement mixture into pet supplements; wherein the second melting point is different than the first melting point and the supplement has a viable probiotic microorganism count of at least about 10⁵ colony forming units (CFUs) per gram of composition.
 15. The method of claim 14, wherein the first fat component is melted prior to mixing with the probiotic component and cooled to a temperature of 110° F. or lower prior to mixing with the probiotic component.
 16. The method of claim 14, wherein the first fat component is held in a melted state for 8 hours or longer prior to mixing with the probiotic component.
 17. The method of claim 14, wherein the temperature during mixing of the sweetener component and the homogeneous mixture of probiotic component and first fat component is maintained at from 100 to 105° F.
 18. The method of claim 14, wherein at least the mixing of the first fat component and the probiotic component is conducted in a conditioned room or chamber maintained at a temperature of about 100° F. and a relative humidity of 10% or lower.
 19. The method of claim 14, wherein the mixing of the sweetener component to the homogeneous mixture of probiotic component and first fat component occurs in at least two steps.
 20. A pet supplement consisting of: an amount of probiotic microorganisms and a first fat component having a first melting point; and a sweetener component comprising sugar and a second fat component having a second melting point; Wherein the second melting point is different than the first melting point and the supplement has a viable probiotic microorganism count of at least about 10⁵ colony forming units (CFUs) per gram of composition.
